Description

Technical Field

[0001] This utility model specifically relates to a precast bridge pad stone platform that facilitates adjustment of cross slope. Background Technology

[0002] Bridge pad stones are concrete structural components located on top of bridge piers and abutments to support the bridge superstructure. They are crucial force-transfer components in bridge structures. During bridge construction, due to factors such as construction errors, the actual elevation of the piers and abutments may deviate from the design elevation. Bridge pad stones can compensate for this deviation by adjusting their thickness, ensuring that the installed beams achieve the required elevation and slope, thereby guaranteeing that the bridge's alignment meets design standards.

[0003] Typically, during the prefabrication of bridge pad stones, small prefabrication pad stone processing plants are built in advance near the bridge or in the middle of the span to facilitate transportation. After prefabrication, the prefabricated pad stones are transported to the site for installation. During the prefabrication process, in order to save costs, idle steel formwork of suitable size and quality is often used as the prefabrication pad stone platform. However, since the cap beam has a unidirectional or bidirectional cross slope, in order to ensure that the top of the pad stone is level after installation, the bottom transverse height of the pad stone also needs to be adjusted with the cross slope of the cap beam during prefabrication. That is, the cross slope of the platform is adjusted to be consistent with the cross slope of the cap beam in advance. However, it is not convenient to adjust the cross slope of the platform during on-site prefabrication, which can easily lead to uneven load distribution in various parts of the pad stone, making it prone to cracks and reducing the overall load-bearing capacity of the pad stone. Furthermore, if the top slope of the pad stone does not meet the requirements, the beam will not be at the designed slope, resulting in tilting, affecting traffic safety. In addition, after long-term use, it will also lead to premature damage to the bridge bearings and increase bridge maintenance costs.

[0004] Therefore, it is necessary to invent a bridge pad stone precast platform that is easy to adjust the cross slope to solve the above problems. Utility Model Content

[0010] The cross slope adjustment assembly includes a main base, on both sides of the main base corresponding to the positioning rod assembly, and the support seats on both sides are located inside the main base, that is, the platform body is installed on the main base. A transverse groove is also provided below the fixing groove, and an adjusting rod is provided at both ends of the transverse groove.

[0013] Preferably, the maximum extension distance of the telescopic rod should at least exceed the midpoint of the transverse groove.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4 The bridge pad stone prefabrication platform shown is easy to adjust the cross slope, including a platform body 1, a plurality of template groups 2 for bridge pad stone prefabrication on the platform body 1, and a cross slope adjustment component 3 below the platform body 1.

[0030] Specifically, the base body 1 has support seats 11 on both sides of the bottom, and mounting holes 12 are provided on the support seats 11 on both sides. A positioning rod assembly 13 is inserted between the mounting holes 12 on both sides, and a positioning rod assembly 13 is provided at both ends of the support seat 11.

[0031] Reference Figure 2 The cross slope adjustment component 3 includes a main base 31. The main base 31 has fixing grooves 32 on both sides corresponding to the positioning rod components 13, and the two side support seats 11 are both located inside the main base 31. That is, the platform body 1 is installed on the main base 31. A transverse groove 33 is also provided below the fixing groove 32. Adjusting rods 34 are provided at both ends in the transverse groove 33. One end of the adjusting rod 34 is connected to the telescopic component 4, and the adjusting rod 34 contacts the bottom surface of the support seat 11 when it moves in the transverse groove 33.

[0032] Specifically, the support base 11 has a T-shaped overall cross-section, with its bottom ends set as arc surfaces. When the support base 11 is installed inside the main body base 31, its bottom surface extends at least beyond the top surface of the transverse sliding groove 33. That is, the adjusting rod 34 presses against the bottom surface of the support base 11, and the contact point between the adjusting rod 34 and the arc surface of the support base 11 is below the midpoint of its arc surface.

[0033] In this embodiment, the support seats 11 on both sides of the bottom of the pedestal body 1 are aligned with the inner side of the main body base 31. The support seat 11 has a T-shaped cross-section. When inserting it into the main body base 31, ensure that the bottom surface of the support seat 11 at least exceeds the top surface of the transverse groove 33. Pass the positioning rod assembly 13 through the mounting hole 12 on the support seat 11, and insert both ends of the positioning rod 131 into the fixing groove 32 on the main body base 31. Both ends of the positioning rod 131 should extend beyond the outer side of the fixing grooves 32 on both sides to leave room for the installation of the fastening nuts 133. Then, put the fastening nuts 133 on both ends of the positioning rod 131 and tighten them, thus completing the installation of the pedestal body 1 on the main body base 31.

[0034] Reference Figure 4 The main base 31 is provided with mounting grooves 35 at both ends. The telescopic component 4 is installed in the mounting groove 35. The telescopic component 4 includes a mounting sleeve 41, which is sleeved on the outside of the adjusting rod 34. Multiple telescopic rods 42 are fixed on one side of the sleeve. One end of the multiple telescopic rods 42 is connected to a telescopic cylinder 43, which is fixed on the outside of one end of the main base 31.

[0035] Specifically, the maximum extension distance of the telescopic rod 42 should at least exceed the midpoint of the transverse groove 33.

[0036] In this embodiment, telescopic components 4 are installed in the mounting grooves 35 at both ends of the main body base 31. First, the mounting sleeve 41 is fitted over the adjusting rod 34, and then one end of one of the multiple telescopic rods 42 fixed on one side of the mounting sleeve 41 is connected to the telescopic cylinder 43, which is fixed to the outside of one end of the main body base 31.

[0037] Reference Figure 3 The positioning rod assembly 13 includes a positioning rod 131. Both ends of the positioning rod 131 are provided with threads 132 and the ends are fitted with fastening nuts 133. Both ends of the positioning rod 131 should extend at least beyond the outer side of the two fixing grooves 32 and leave space for the installation of the fastening nuts 133. The overall shape of the fixing groove 32 is arc-shaped, which corresponds to the movement trajectory of the overall cross slope adjustment of the platform body 1.

[0038] Reference Figure 4 The adjusting rod 34 is also provided with baffles 36 at both ends. The baffles 36 are located outside the transverse groove 33, and the overall length of the adjusting rod 34 should at least meet the distance between the two transverse grooves 33.

[0039] Specifically, the internal length of the main base 31 should at least allow the support base 11 to be fully inserted, and leave space at both ends for the adjustment rod 34 to be retracted.

[0040] In this embodiment, when the cross slope of the platform body 1 needs to be adjusted, the telescopic cylinder 43 is activated. The telescopic cylinder 43 extends and retracts, causing the telescopic rod 42 to move. Since the telescopic rod 42 is connected to the mounting sleeve 41, which is fitted over the adjusting rod 34, the adjusting rod 34 moves within the transverse groove 33. When the adjusting rod 34 moves within the transverse groove 33, it contacts and presses against the bottom surface of the support base 11. Because the bottom ends of the support base 11 are curved, and the contact point between the adjusting rod 34 and the curved surface of the support base 11 is below the midpoint of its curved surface, this structural design allows the movement of the adjusting rod 34 to effectively change the height of the support base 11. Since the adjusting rods 34 on both sides can move independently (controlled by their respective connected telescopic components 4), the cross slope of the platform body 1 can be adjusted by controlling the different displacements of the adjusting rods 34 on both sides. For example, if one adjusting rod 34 moves outward (away from the center of the platform), while the other adjusting rod 34 remains stationary or moves inward (closer to the center of the platform), the platform body 1 will develop a cross slope. The adjusting rod 34 is equipped with baffles 36 at both ends, which are located outside the transverse sliding groove 33. This prevents the adjusting rod 34 from moving excessively within the transverse sliding groove 33 and dislodging it. The maximum extension distance of the telescopic rod 42 should at least exceed the midpoint of the transverse sliding groove 33, ensuring that the adjusting rod 34 has sufficient range of motion to achieve a large-scale transverse slope adjustment. Simultaneously, the internal length of the main base 31 should at least allow the support base 11 to be fully inserted, with space at both ends for the adjusting rod 34 to retract. This provides sufficient space for the movement of the adjusting rod 34, ensuring smooth transverse slope adjustment operations.

[0041] In this embodiment, precise control of the adjusting rod 34 via the telescopic component 4 enables accurate adjustment of the cross slope of the pedestal body 1. Since the movement of the adjusting rods 34 on both sides can be controlled separately, it can meet the prefabrication tasks of bridge pad stones with various cross slope requirements. For bridge pad stone prefabrication with specific cross slope requirements, the cross slope of the pedestal body 1 can be accurately adjusted to meet the requirements. The telescopic cylinder 43 has a relatively fast extension and retraction speed, so when cross slope adjustment is needed, the adjusting rod 34 can be quickly moved within the transverse sliding groove 33, thereby rapidly changing the cross slope of the pedestal body 1. This can improve production efficiency in prefabrication processes that require frequent cross slope adjustments.

[0042] In this embodiment, during installation, the pedestal body 1 is stably installed on the main base 31 through the positioning of the positioning rod assembly 13 and the tightening action of the fastening nut 133. This stable installation structure ensures that the pedestal body 1 will not shake or shift during prefabrication, thereby ensuring the accuracy of bridge pad stone prefabrication. During the cross slope adjustment operation, although the adjusting rod 34 moves within the transverse groove 33, the entire structure remains stable during cross slope adjustment due to the baffles 36 at both ends of the adjusting rod 34 and the reasonable space design between the components. This ensures that the quality of bridge pad stone prefabrication is not affected even when the cross slope is adjusted during the prefabrication process.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
